And this is why they employ their time in setting the union against the political party of the working class, the only union labor party there ever was or ever will be, and warning the members against the evil designs of the socialists. The important thing to impress upon the mind of the trade-unionist is that it is his duty to cultivate the habit of doing his own thinking. The moment he realizes this he is beyond the power of the scheming politician, the emissary of the exploiter, in or out of the labor movement. The trades-union is not and can not become a political machine, nor can it be used for political purposes. They who insist upon working class political action not only have no intention to convert the trades-union into a political party, but they would oppose any such attempt on the part of others. The trades-union is an economic organization with distinct economic functions and as such is a part, a necessary part, but a part only of the Labor Movement; it has its own sphere of activity, its own program and is its own master within its economic limitations. But the labor movement has also its political side and the trades-unionist must be educated to realize its importance and to understand that the political side of the movement must be _unionized_ as well as the economic side; and that he is not in fact a union man at all who, although a member of the union on the economic side, is a non-unionist on the political side; and while striking for, votes against the working class. The trades-union expresses the economic power and the Socialist party expresses the political power of the Labor movement. The fully developed labor-unionist uses both his economic and political power in the interest of his class. He understands that the struggle between labor and capital is a _class_ struggle; that the working class are in a great majority, but divided, some in trades-unions and some out of them, some in one political party and some in another; that because they are divided they are helpless and must submit to being robbed of what their labor produces, and treated with contempt; that they must unite their class in the trades-union on the one hand and in the Socialist party on the other hand; that industrially and politically they must act together as a class against the capitalist class and that this struggle is a class struggle, and that any workingman who deserts his union in a strike and goes to the other side is a scab, and any workingman who deserts his party on election day and goes over to the enemy is a betrayer of his class and an enemy of his fellowman.
